RE: Seagull's
kiosk,
Sorry.....can't help you out on the JR.
Somewhere here at RCU, I did a step-by-step procedure for setting up dual engine controls using a Futaba. Step #1: You must have a newer Futaba having at least 8 channels. I use the spring-loaded trainer switch to kill both engines at the same time.
If any Futaba owners are interested, I can look it up and post a link.
